HS code for Chemical mixtures: 3824.99

Chemical products, mixtures and preparations, n.e.c. heading 3824.

Classification of chemical mixtures under HS 3824.99

Chemical mixtures and preparations not elsewhere specified or included are classified under HS code 3824.99. This is a "basket" subheading within heading 3824, which covers a wide array of chemical products from the chemical or allied industries. Classification here is often a result of the product not meeting the criteria for more specific headings in Chapters 28 through 38. According to GIR 1 and 6, products are classified in 3824.99 if they are mixtures of two or more substances or preparations that do not have a more specific heading. This includes industrial chemical blends, specialty additives, and various technical preparations used in manufacturing. The Explanatory Notes for heading 3824 emphasize that this heading includes products whose composition is not chemically defined or those that are mixtures. It excludes products that are classified as medicaments (3003 or 3004), food preparations (Chapter 21), or those with a specific function covered by other headings (such as insecticides in 3808). Because 3824.99 is a residual category, it requires a thorough exclusionary analysis to ensure no other heading applies before assigning this code.

Codes often confused with 3824.99

Common mistake. The most common misclassification involves HS code 3824.91, which is specifically for mixtures and preparations containing oxiranes (ethylene oxide), or 3824.71-3824.79 for mixtures containing halogenated derivatives of methane, ethane, or propane. Importers often default to 3824.99 without checking for these specific chemical components. Additionally, if a mixture has a specific use as a diagnostic reagent, it should be classified under 3822.00. If it is a prepared binder for foundry molds not based on the specific materials in 3824.99, it might fall under 3824.10.

Top exporters and importers of HS 382499 (the code used for chemical mixtures), 2025

In 2025, the largest exporter of HS 382499 (the code used for chemical mixtures) in UN Comtrade data was China, with 15% of world exports; the largest importer in UN Comtrade data was China, with 15% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

Figures cover everything classified under HS 382499, not only chemical mixtures.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
